Latest numbers from Quinnipiac University Poll also show little support for a federal crackdown in states that have legalized cannabis.

An increasing number of Americans are in favor of national legalization of recreational and medical marijuana, and few support a federal crackdown in states that have legalized marijuana for either purpose.

A new Quinnipiac poll released August 3 reported that medical marijuana in particular has broad support: 94 percent of Americans support “allowing adults to legally use marijuana for medical purposes if their doctor prescribes it,” up from 93 percent 5 months ago, and up 5 points in the last year.
